Ad 2) @splat21 sorry for the confusion: that is 2.93. Geometry Nodes develops really fast these days. This was just a fast demonstration of the principle, so I cheated and used a version ‘from the future’.
Of course, for the COLLAB we will stick to 2.92, but there are enough Nodes there to make something like this work.
And you do not need to delete the Group Input Node; I just left it unconnected (it was a Plane and I didn’t want to show it here…) The GN Tree needs to be connected to an Object. A bit like a Particle System, where you can decide to not show the Emitter.
In 2.92 you could just use an Icosphere and add the GN Modifier (Node Tree) to that!
in the Geo Node world, is this considered a “shader” node (e.g., it has green connections)?
absolutely not!
Those colors are independent from Shader Editor Colors.
Although Purple still means Vector and yellow color, but Grey means float(ing point number).Turquoise/green is used for Geometry and green for integers. Then there is white for a Collection, pink for a Boolean and blue for a String:
But these color may still change, as this is in early development.
If you want to learn more about GN look for Erindale on YT. He has some wonderful tutorials for beginners.
He also made this (only modeled a few leaves for the flowers, the rest is GN):
@spikeyxxx I played around with this a little more in 2.92 and got it to work.
I used a Floor instead of your Ceiling as I wanted the subdivision Level value to be 0 when the camera is furthest away. The 2nd Divide function was to dial in a little more granularity – it’s value would need to be tweaked per the actual application. Here are my camera zooms at different locations.
1) Can you please tell my why you used the value of 10.3 when you divided it by the distance vector? What is magical about 10.3?
2) Is this how you would have approached this problem in 2.92? Specifically, using the Mesh Subdivision Surface node. Is there a better way?
3) It would be helpful to be able to monitor the output value of the math nodes. Kind of like a debugger that monitors floating point, integer and Boolean variables. Are you aware of any provisions to display such information within Blender? Sorry, I have not looked into the future at 2.93 to see if there is that kind of a node there.
Again, thanks for your assistance in helping me to learn this.
Ad 1) there’s nothing magical about it just a more or less random value that gave an exaggerated effect. So in stead of using two Divide Nodes, you can use one with a different value.
Ad 2) i don’t think there is a better way to make this example….
Ad 3) in 2.93 there is a Spreadsheet:
And I used Ceiling in my example, because the Primitive Icosphere in 2.93 doesn’t have a zero Subdivisions (at least, it is the same as 1 Subdivision):
